Calliandra leaf pellets
With an estimated leaf volume of 1/4 of the wood but the price of leaf pellets is around 3 times the price of wood pellets. So the profit from utilizing leaves into pellets (leaf pellets) is very big, estimated at 1/2 to 3/4 of the turnover of wood pellets. Whereas calliandra leaves are usually only considered by-products or waste in energy plantations.
And almost the same as gliricidia leaf pellets, if these plants are planted in the energy plantation.
As a reference for indigofera zollingeriana leaf pellets:
Both calliandra, gliricidia and indigofera are groups of legume plants whose leaves are suitable for animal feed rich in protein. Protein is the most expensive nutrient element in animal feed.
